Not a problem at all.
If you don't currently have access to your account, you can hover your mouse over the "Sign In" and click "My Hub". Then you can click "Forgot Password" and enter the details there.
If you are already logged in, you can simply go to your "My Hub" section and click "Change Password" on the top right of the "Contact Info" box at the bottom of the page.
You do realize that when you select the "Change Password"
it asks you for your "current password" and then the new password. WELL... What if you don't remember your "current password"? I have yet found a way to change my passord BECAUSE I don't recall my current one.
